Each diode is about 1/4 inch in diameter and uses about ten milliamps to operate at about a tenth of a watt. LEDs are small in size, but can be grouped together for higher intensity applications. LED fixtures require a driver which is analogous to the ballast in fluorescent fixtures. The drivers are typically built into the fixture (like fluorescent ballasts) or they are a plug transformer for portable (plug-in) fixtures. The plug-in transformers allow the fixture to run on standard 120 volt alternating current (AC), with a modest (about 15 to 20 percent) power loss.
The efficacy of a typical residential application LED is approximately 20 lumens per watt (LPW), though efficacies of up to 100 LPW have been created in laboratory settings. make sure to examine system efficacy, which accounts for the power use of all components. In December 2006, the U.S. Department of Energy studied the efficacy of four luminaries. All four fell short of the manufacturers’ claims; the study implies that manufacturers are relying on measurements of how much light an isolated LED produces, rather than how much light an LED luminaire actually delivers.
LEDs are better at placing light in a single direction than incandescent or fluorescent bulbs. Because of their directional output, they have unique design features that can be exploited by clever designs. LED strip lights can be installed under counters, in hallways, and in staircases; concentrated arrays can be used for room lighting. Waterproof, outdoor fixtures are also available. Some manufacturers consider applications such as gardens, walkways, and decorative fixtures outside garage doors to be the most cost-efficient.
LED lights are more rugged and damage-resistant than compact fluorescents and incandescent bulbs. LED lights don't flicker. They are very heat sensitive; excessive heat or inappropriate applications dramatically reduce both light output and lifetime. Uses include:
The long lifespan of LED High Power Spot Lights is 20,000Hrs compared to the diminutive 3000hrs life expectancy of standard Mercury lamps. The predicted power savings rate is 85%.
Home security:
The LED High Power Spot Lights can easily replace traditional mercury spotlights. They are similar in appearance as well as size, and bring considerable advantages that only LED lamps and spotlights can bring. With the low power, comes low heat and thus they are available for more uses due to the fact that they do not get as hot as their traditional mercury counterparts. The added benefit of low power consumption as well as a lack of potentially dangerous byproducts such as heavy metals makes the GlacialLight GL-Spotlight (60W) the best choice for your home environment bringing savings for years to come.
Super High Power LED PAR30 and PAR 38 provide all of the freedoms of traditional incandescent lamps and allow these energy efficient light sources to set a variety of moods and ambience for today's interiors.
The Super High Power Dimmable LED PAR30 produces 500 lumens and is a direct replacement for a 65-watt BR30 or a 50-watt PAR30 halogen bulb. The Super High Power Dimmable LED PAR38 produces 743 lumens and is a direct replacement for a 100-watt BR40 or a 75-watt Halogen PAR-38 bulb. Both new Super High Power Dimmable LED PAR bulbs are engineered with a Super High Power chip that provides the brightest and best quality LED light output.
This all-weather luminaire offers an extended LED lamp life, maintenance-free operation, long-lasting durability, major energy savings, and reduced light pollution, all translating into reliability, ecological sustainability and sizable budget savings. Standard wall-pack luminaires are notorious for reduced control of light output because of their poor optical configuration, contributing to light pollution, wasted uplight and a shallow light projection. The high-power LED lamp Wall-Pak’s design achieves a much more efficient illumination coverage — The optical center of the lens is aligned with the lamp source for an even symmetrical distribution of light that redirects light to minimize glare. It effectively sends a wide-focused circular beam of around 85 degrees that spreads 157 degrees vertically and 38 degrees horizontally.
The design and fabrication of this LED based lighting system took approximately 6 months from start to finish. As you may have read already, the goal was to match the light output of a 32 watt T8 fluorescent lamp while using significantly less energy. This is an ambitious task because T8 fluorescent lamps are the more efficient flavour of this technology. LED Tube that were designed are intended to run on sealed lead-acid batteries which means they can accept an input voltage of anywhere from 10.5 V to 13.5 V. This input voltage was chosen to make LED Tube compatible with solar or wind energy systems. This means that if your home or building is operating on solar or wind energy, you can connect LED Tube directly to the batteries and bypass the inverter. This allows you to purchase a smaller inverter and requires you to have less solar panels (due to the energy loss when converting from 12 VDC to 120 VAC).

An ever-growing trend, LED programmable displays are the fastest way to communicate critical information to parents and students. They offer an energy-efficient and aesthetic vehicle for schools, towns, restaurants and retail businesses to exhibit real-time information. Board of Education updates the sign several times a week with messages about openings, closings, upcoming events, and general communications for parents and students.
